Observations on vesico-ureteric reflux and intrarenal reflux: a review and survey of material
Insights
Vesico-ureteric reflux and intrarenal reflux in children with urinary tract infections are influenced by age, race, and diuretic use, but not significantly by sex or examination technique. Intrarenal reflux, seen in 10% of total reflux cases, doesn't appear to cause scarring independently.
Area of Science:
- Pediatric Nephrology
- Urology
- Medical Research
Background:
- Urinary tract infections (UTIs) are common in children, with vesico-ureteric reflux (VUR) a significant concern.
- Understanding factors influencing VUR and intrarenal reflux (IR) is crucial for pediatric kidney health.
- Existing literature on VUR and IR requires synthesis and evaluation of influencing factors.
Observation:
- Vesico-ureteric reflux affects 33-50% of Caucasian children with UTIs.
- Intrarenal reflux occurs in approximately 10% of patients with total reflux.
- Autopsy studies offer insights into papillary morphology but have limitations in early infancy and preserved specimens.
Findings:
- VUR prevalence is influenced by age, race, and diuretic administration.
- Examination technique and sex show minimal impact on VUR detection.
- Intrarenal reflux does not appear to cause renal scarring in isolation.
Implications:
- Age, race, and diuretics are key factors to consider in VUR assessment.
- Further research is needed to clarify the role of intrarenal reflux in renal scarring.
- Clinical management of pediatric UTIs should account for identified VUR influencing factors.
Abstract:
Objectives of this study were to evaluate some of the factors influencing vesico-ureteric reflux and intrarenal reflux. Reflux occurs in about one-third to a half of Caucasian children with urinary tract infection and although not greatly influenced by examination technique or sex it is affected by age, diuretics and race. Intrarenal reflux occurs in about 10% of cases with total reflux and does not appear to cause scars on its own. Autopsy studies can provide valuable information on papillary morphology and reaction to pressure, but information is of doubtful reliability in the first months of life and in fixed specimens. The literature pertaining to vesico-ureteral reflux, intrarenal reflux and related research projects is briefly reviewed.
